Quality Standards

All Gobel Power batteries (GP-SR1) must undergo rigorous full cycling tests before being shipped. Some standards for battery with LSEV cells are:

• The maximum charging voltage when a single cell triggers overvoltage protection: ≥56V (The standard ensures that all battery cells possess commendable uniformity. The lower the voltage value, the poorer the consistency.)
• The minimum discharge voltage when a single cell triggers low voltage protection: ≤44V (The standard ensures that all battery cells possess commendable uniformity. The higher the voltage value, the poorer the consistency.)
• Capacity: ≥280Ah

The presented classification method above aims to assess the quality of different batteries, focusing on their maximum charge voltage. This parameter serves as an indicator of the cells' consistency within the battery. Specifically, a higher level of cells consistency corresponds to a higher maximum charge voltage.

Cell consistency refers to the uniformity in performance and characteristics among individual cells within a battery pack. In the context of a lithium iron phosphate (LiFePO4) battery, this means that each cell in the battery should ideally have the same capacity, internal resistance, self-discharge rate, and other key parameters.

The importance of cell consistency in a LiFePO4 battery lies in its impact on the overall performance and lifespan of the battery. When cells are consistent, the battery can deliver its power more efficiently, and it is less likely to experience premature aging or failure.

This is because when cells are inconsistent, the weaker cells can become overworked as they try to keep up with the stronger ones, leading to faster degradation. Furthermore, inconsistent cells can result in imbalanced charging and discharging, which can cause some cells to become overcharged or over-discharged, potentially leading to damage or even failure of the entire battery pack.

Therefore, maintaining cell consistency is a critical aspect of battery design and management, ensuring optimal performance, safety, and longevity of LiFePO4 batteries.
